Interesting question. It seems that the only time you see Fences.exe is when you click on Configure fences in the desktop context menu. Then it is 18MB. When double clicking the desktop to make the fences disappear the explorer.exe Image pops up in the top CPU users for a quick time. Outlining for a new fence also causes Explorer to popup to the foreground.

I have used this program for about 6-9mo and like it. I also have clients with messy desktops who also like it.

i should probably start a new topic since in reality i would like to know which of three might tax my system less ; rocketdock (which im very familiar with, cause i used it for a good while in the past), fences which im playing around a little with right now, and objectdock that ive never used.
I CANNOT FIND a comparison or details about what the footprint of either one of these is. Ugh!

EDIT:
i know my system is not half the monster of what some of you guys roll with but what do you think. / besides actual testing, how can someone look at that versus a machines specs and figure more or less if its wasted energy.
another thing to note of course is that i have disabled a good bunch of services and processes so i do have a little reserve. no aero for example - standard theme (which youve probably noticed from screenshots - etc.,etc.,) and the list gos on.

I got 20MB once but another time I got the 18MB. I was interested enough to get up and go downstairs to my computer with fences on it to see if I could find it, but beyond that I really don't care, lol.
